This article describes the construction of a complete experimental apparatus to simulate the greenhouse and global warming for educatioal use. These demonstrations are fundamental for people understand the importance of greenhouse effect to keep that life continues on earth and, know about climate change and the causes of global warming. For development of this devise we used an Arduino UNO, temperature and pressure sensors, and low cost products. The experimental results showed that the average atmosphere temperature increases with the increasing concentration of carbon dioxide (CO2). Moreover, this apparatus can be used in classroom to demonstration these important global phenomena.
